ABSTRACT:
A carrier capable of carrying elongated materials without bending or folding through conventional pneumatic tube systems which include a passageway having a predetermined inner cross-sectional dimension wherein the passageway includes curvatures having a predetermined radius. The carrier has a length greater than the maximum length of standard carriers which are currently used in conventional pneumatic tube systems. The carrier includes a first elongated member having an open end and a tapered closed end, a second member having an open end and a tapered closed end, the open ends of both the first and second members including cooperating threads for securing the members to each other to provide a closed elongated compartment, each of the members having an outer cross-sectional dimension which is smaller than the inner cross-sectional dimension of the passageway to allow passage of the elongated compartment through the tube curvatures without engaging the inner surface of the passageway, and each of the members further includes an accelerator ring for engaging the inner surface of the passageway, each of the accelerator rings having an outer cross-sectional dimension which is generally equal to the inner cross-sectional dimension of the passageway and a width which is small relative to the overall length of the elongated compartment.
